WILLIAM s. xELLeee, an, or rEoaIA, ILLINOIS.

To all whom it may concern Be it known that I, WILLIAM S. KnLLoee, Jr.,a citizen of the United States, res1ding at Peoria, in the county ofPeoria and have invented certain new and useful Improvements inCarbureters, of which the following is a specification.

My invention relates to carbureters. The object of my invention is toprovide a carburetor operating wholly under the influence of a currentinduced by the en gine to apply a uniform quality of mixture withoutregard to the speed at which the engine is run.

Another object of my invention is to provide means for controlling themixture of air and the liquid base to produce the desired mixture.

My invention consists in the provision of a combined float andcarbureting chamber, means for raising the liquid base to the inducedcurrent through the carbureting chamber, means for controlling theliquid exposure to the air current and for mixing the same, and otherdetails of construction hereinafter more particularly described.

Referring to the drawings-Figure l is a side elevation showing thegeneral form of the device; Fig. 2 1s a Vertical sectional view on theline 22 of Fig. 1; Fig. 3 is a side elevation with parts broken away toshow interior construction; Fig. 4 is a top view on the line H of Fig.1; Fig. 5 shows one form of a templet, and Fig. (3 shows another form ofa tempiet.

Referring to the figures, A refers generally to a combined float andcarbureting chamber formed of two sections 2 and 3 adapted to be joinedtogether in any suitable manner to render-the joint therebetweenperfectly air and gas tight. The liquid fuel base is designed tobe,carried in the lower portion of section 2 and the flow. of liquid intosaid section is controlled by float 4c in the usual well known manner.

5 is an air inlet into the carbureting portionof the carbureter and 6 isa mixture the engine, the" air inlet and mixture outlet being preferablyarranged in different horizontal planes.

7 is a disk adapted to be arranged within the combined float andcarbureting chamber in substantially the relation shown.

7 are perforations through the body of the disk which I have showp .asangularly Specification of Letters Patent.

disposed with relation to the air inlet and mixture outlet or both.

8 is a spindle to which disk 7 is fixed and which is provided at itsends with cone points 9, the respective ends adapted to be supported incone bearings in set screws 10 and 11, the latter being carried insuitable threaded openings in the body of the chamber in substantiallythe relation shown.

The mixture outlet is controlled by but terfly valve 12 which issupported 011 suitable spindles journaled in the walls at the mouth ofthe opening out of the carbureting chamber, the movement of said valvebeing adapted to be controlled by the op- 13 fixed upon 18 refersgenerally to a. templet portion of a brake arm connected through castpart arm 19, said teniplet being preferably formed as shown in eitherFigs. 2, 5 or 6 according to the associated use with different engines,in which figures the face 20 is formed straight and the face 21 camshaped. The cast portion 22 of the com plete brake arm is adapted to befixed in an adjustable relation in connection with crank arm 19 withinslot substantially as shown in Fig. l. The lower portion of arm 18 isadapted to depend through slot 24 in cast extension 17 and the face 20of said arm has normally a bearing relation with push rod 15. Theinitial position of arm 18 with relation to push rod 15 is adapted to bcfixed by means of set screw 25 substantially 'l helyform of the camVariation, can be determinedonly by test, and is accomplished by firstwith relation to the screw 25 and push rod 15 to proper workingcondition on low speed. Then the valve is openmlstep by step with theincrease of speed. Then by av series of tests to determine theadjustment at points intermediate the extremities of the templet, therequired variation of distance.

setting the arm llO between the faces 20 and 21 of said templet will bealso determined. Commonly, if not uniformly, the most abrupt brakingeffect will occur at the beginning of the opening of the butterfly valveand thereafter the increased braking etl'ect required will be ordinarilyvery gradual up to the point of the complete opening of said valve.

The form of the float chamber and carbureting chamber, and in structurethat forms said chamber may be varied to suit the requirements of useexcept that they shall be in communicating relation. The air inlet andmixture outlet openings likewise may be modified to accommodate varyingconditions of use. The brake mechanism adapted to control the speed ofdisk? may be in any suitable form to accomplish the purpose, forinstance, the construction may be such that push rod 15 may have adirect bearing upon the face of disk 7.

I have shown in the drawings a brake mechanism adapted to control thespeed of wheel 7. However, under certain conditions of use this brakemechanism may be dispensed with entirely. For instance, a carbureter maybe associated with engines of a certain uniform and defined structure.In such case the combined area of the perforations in disk 7 and that ofthe air inlet may be so proportioned that the disk wheel will beautomatically cont-rolledand its speed confined within limits consistentwith the working c-.nnbination in which it is used, to produce a uniformquality of mixture throughout the variations of speed at which theengine is run. The brake mechanism is provided merely to render a singletiillbllreter adaptable for use in connection with any engine. 1

in operation. the parts having been adjusted in the. relative positionsshown in the drawings, the initial starting of the engine having beenaccomplished and the butterfly valve 1; opened. as thepistons of theengine are. rcciln'm'utcd. a current of-air is induced through air inlet5, perforations '4' of the disk wheel 7 and through mixture outlet (3,and from thence into the engine cylinder. The action of the. air beingdrawn through openings 7 will cause disk 7 to be rotated, serving toraise. the liquid base into contact with the air passing through thecarbureting chamber and as it is thinly spread upon the surl'acc ofthcdisk' and upon the walls of the. perforations. it is readily taken upby the air. and as almost ercry particle of air passing through thechamber is brought into contact with liquid in condition for readyvaporization, a perfectly natural mixing occurs that renders the mixtureperfect withoutauxiliarv mixing means. at least in the ordimirilv low ormoderate speeds of the speed of the engine 1nengine. ;'\s the.

fact the combined,

creases the speed of rotation of disk 7 will be proportionatelyincreased, serving to equalize'the exposure of liquid to the air currentin proportion to the increased flow of air through tne carburetingchamber, thus insuring a proportionate mixture. of the two basicelements of the mixture that will effect a constant uniformity ofmixture. The flow of mixture into the engine is always under control ofthe operator through and by proper manipulation of the butterfly valve,as is well understood.

As previously of perforations 7 in disk 7 is properly pro portioned tothe size of the air inlet, no con trol mechanism is needed to limit thespeed of said disk. However, as also previously stated, in order to meetthe varying conditions of use of a carbureter with any engine, a controlmay be found necessary.

The operation of the control mechanism is as follows: The proper.adjustment of brake arm 18 having been made with relation to push rod15, the opening of the butterfly valve to admit an increased flow of airwith an accompanying increase in the speed of the engine would result inan increased speed of disk 7. Because of the disk having a free supportupon its bearingfthis would result normally in a proportionately greaterspeed of said disk than that of the increased flow of 1 airtherethrough. To check this normal tendency to greater proportionatespeed, the brake mechanism is connected up with-butterfly valve 12 sothat as it s opened the brake arm 18 is depressed,

and being in bearing relation with push rod 15 pushesthe la ttcr intofrictional brake contact with auxiliary disk ll. The form of the brakearm is such that with the increased opening of the lmttertlyw valvethere will be,

exerted a greater brake force applied to auxiliary disk force beingadapted to be such as to confine the speed of disk '7 within a certaindefined limit so as to prevent too great an agitation of the liquidwithin the carbureting chanr ber.

It may be that other mechanical means mi ght be employed to raise themixture base to-thecourrent passing through the carburet ing chamber andto agitate the same within certainpractical limits, and it may be thatthe relative positions .of the air inlet and mixture outlet may be suchtoperforations in the disk thatsubstantially straight peril, suchproportionatebrake" stated, if the combined area f forat-ious at rightangles with the faces of the disk may be employed and still induce thedesired rotation therein, therefore 1 do not 'vish to confine myself tothe particular detail structure which I have herein shown and described,but it is my desire that it shall. comprehend a'ny'and all forms of errbodim'eutpf my invention that fall legiti ii'iately withinthe principleth'ereoi.
